Chroma-wings represented the ultimate phase in the life cycle of the Ruurian sentient species. As Ruurians reached their later years, they would cast off their larval bodies and encase themselves in a cocoon. This process turned them into exquisite chroma-wings, creatures driven only by the needs of eating, mating, and gracefully soaring above the riverbanks of Ruuria. Despite the Ruurians viewing this metamorphosis as an idyllic existence, they possessed the means to halt their transformation into chroma-wings, utilizing ointments, prescribed medications, and specialized therapies. Furthermore, Ruurians in their larval stage had the option of undergoing cybernetic enhancements, allowing them to preserve their memories even after becoming chroma-wings. The Ruurian doctor Woolif underwent this type of augmentation, ensuring he retained his medical expertise following his transformation. In contrast, Slyyth, a Ruurian criminal, harbored a deep fear of becoming a chroma-wing, as he desired to continue his criminal activities, and therefore underwent treatments to impede the transformation.
